IMPROVE!) cLoTHEswmNGER.

The Schedule referred to in these Letters Patent and making pan of the same.

To ctllzohomitmcyconccrlt: vh h i Be it known that4 I, ELBRIDGE G. W. BARTLETT, of the city and county of Providence, in` the State of e `Rhode Island, have invented;` a new. and -useful Improvement in Glothesewringers; landldo hereby declare that the following specification, taken in coni nection with the drawings makingapait ofthe same,

is` a full, clear, and exact description thereof.

Figure 1 is a front `elevation ot' a clotheslwringer with my improvement.` i h h h `Figure 2 is a sideyiew of the driving-gear for the squeezing-rollers andthe clearing-roller.

Figure is an improved clamp used with such niachilies.

"A-machinc for wringing `water from clothes, asis `well known,- consists in general;` of a pair of rollers, i,

elastic and impervious. to water, placed.parallelwith eachother, and havingwheir axle-bearings in` upright standards, which `latter Vare tied 'together byeross-4 bars.

One of such rollers is driven by a crank` attachedW to its shaft, and its fellow is inade to revolveeither by -the friction of the clothes in passing between the roll-,`. ers upon itssurt'ace; or by a cog-wheel upon its shaft,.

"the teeth ot' which engage with a cog-wheel upon the crank-shaft of the turning roller.`

` i Sucln rollers are alsoso arranged that their surfaces can be separated for a limited` distance, .to allowA the passage ot' thick folds of clothandthe yielding press-` ureof springs, made adjustable" by pressure-screws,

is also 4applied to the upper rolle', to cause fthe surfaces of the'rollers to squeeze thelclothe'sf h The apparatus is also adapted for attachment, ,at

` Except in the particularshereinafter specified, the

' pleasure, to the side of a wash-tub.

"machine shown in the drawings,corresponds with the weil-known machine above described.V

My tirstiinprovemeut consists in the employment `of a friction driving-gear, to operate the squeezingrollers, inplace of toothed wheels heretofore employed, the advantage of which isthat thc rollers can be allow'ed to separateiiorneach other much farther for i 4the passage of thick folds ot" clotli,"without throwing `the driving-gear out of engagement, than, inmachines employing cog-wheels, would bepracticable.

`.lhe upperroller A has 1a disk-plate,V B, keyedto The lower roller o has maar diskfpiaa, D, :atached to its shaft by alfeather or other means which allow-titte bejmoved along the shaft, but Ilot to revolve around it.

`A clampfnnt, E,` and' also, if preferred, a spring, are placed back of this plate, upon turning which nut the degree of friction which shail exist` between the 'inner face of D and the outer face of B can be increased or diminished, the arrangement of the said diski'plates being such that their contiguous faces shail .bein contact-as shown.` Y

j Fu rt-hermore, it is practically necessary, 1n order to prevenf'thc rollerA binding ii'oin endfpressureagaiust, ,i

its journal, 'to introduce a` disk-plate, K, capable of revolving freely, but with its hub abutting against the side'ot the frame, so as to furnislna {ixed surface, to act inpombuation'with the friction driviugdisk plate D 'uponthe diskrBf i Afurther improvement consists in the employment of ayclearer, .toprevent thin'y articles from taking a4 wrongduection'. audwinding around the lower roller.

It consists of "a third roller,- F, which may be ofv wood, in combination Vwith-the squeezing rollers. x lIn this instance the clearer is iliade to revolve by means of a cog-wheel upon the'shaft of theroller" O,

whose motion 'is communicated to a cg-wheel on the axle; of the clearer, through the pinion G, mounted o'n a stud-pin set in the frame. y

. This clearer, when the machine is in operation, ro-

voires in its bearings H, iu the same direction as the lower roller, whereby articles comingA between the squeezing-rollersfwill bc prevented from winding about the lower roller. v

In piace ofthe clearer. described, a flat stationary-l guard may be used, whose lower edge lis made oncentric with the roller, and placed nearl to the surface ofthe same, so that the ends of'arteles, as they pass be` tween the rollers, will fall naturally upon the top surface of the guard-plate, and be guided away from the lower roller.

VVhat I'claim asmy invention, and desire to secure by Letters Patent, is'.-

`1.l Friction driving-plates B forth. y g 2. A clearer, E, in combination with the squeezingrollers :hf a washing and wringing-machine, geared as shown and described, `for the purposes specified.
